Software inspection has been shown to be an effective defect removal practice, leading to higher quality software with lower field failures. Automated software inspection tools are emerging for identifying a subset of defects in a less labor-intensive manner than manual inspection. This paper investigates the use of automated inspection for a large-scale industrial software system at Nortel Networks. We propose and utilize a defect classification scheme for enumerating the types of defects that can be identified by automated inspections. Additionally, we demonstrate that automated code inspection faults can be used as efficient predictors of field failures and are effective for identifying fault-prone modules.
